28.0.50; Spliced variable not matched as symbol in isearch |
|
Date: |
Tue, 03 Nov 2020 15:38:36 +0000 |
Severity: minor
0. emacs -Q
1. (let (x) `(,@x))
2. M-s _ x
This highlights the bound x, but not the spliced x. The same happens
with 'M-s .' or the equivalent 'C-M-s'.
This is because lisp--mode-syntax-table gives 'prefix' syntax to ?, and
'symbol' syntax to ?@. Is it possible to give 'prefix' syntax to ",@"
as a whole, and in general?
[This behaviour exists since at least as far back as Emacs 24.5.1.
I wouldn't be surprised if this has been reported before,
but my searches came up dry.]
Thanks,

That's fine with me -- now done. Closing bug.
